Ethanol is a type of fuel (found in alcohol) it burns to give arbon dioxide and water. yeast is used to ferment sugars. Sugar cane and sugar beet are used in the production of ethanol.
Cars can be adapted to run on 10% ethanol 90% petrol (gasohol) it requires large amounts of fertile land to grow the crops which means less land for food.
Using gasohol instead of pure petrol means less crude oil is being used. also the carbon dioxide released is balanced out with the carbon dioxide taken out forphotosynthesis.
However distillig the ethanol after fermentation still requires a lot of energy
